DRIVING MEANS FOR DEMOUN'VTABLE RIMS;y j

Application led July 31,

To @ZZ whom t maly concern." Be it known that I, LoUIs B. HARVEY, acitizen of the VUnited States, residing at Buffalo, county of Erie,State of New York, have invented certain new and useful Improvements inDriving Means for Demountable Rims; and I do declare the following t0 bea full, clear, and exact description of the saine, reference being hadto the accom-V panying drawings, and to the characters of referencemarked thereon, which form a part of this application. Y

This invent-ion relates to a driving means between the fixed anddemountable rims of a wheel, the principal object being to form a lug onthe demountable rim which will co-,

operate with lugs on the fixed rim in such a manner that the two rimsVcan have no relative peripheral movement when once placed together. n

Another object is to utilize the lug on the demountable rim as aprotecting sleeve for the tire-valve stem, and'to Vso form 'the fixedrim adjacent the lugs thereon that the demountable rim, with the tirecarried thereby, may be slid onto the fixed rim without the necessity oflifting the tire and its rim in order to enable the valve stem to clearthe xed rim.

On account of this latter construction, this device is especiallyadapted to 'be used for truck wheels using pneumatic tires, since theselatter are very large and heavy, Vand it is no light'tasl: to lift these'heavy tires and rimsto positionthem on the wheel.

rIhe consti-uc ion employed is also especially intended to beincorporated ina lwheel using discs secured directly to the fixed riminstead of spokes and a felly.V I also aim to use my improveddemountable rim as shown in my co-pending application for Patent.gli-284,983, filed March 25th, 1919, and an a'iq valve hand-hole platesubstantially as shown in my vPatent No. 1,338,177, dated April 27th,1920, while the form ofV xed rim and locking ring for the demountablerim is as shown in my co-pending application, Serial No'. 402,079, filedAugust 9th, 1920.

- A further object of the invention is to pro-v duce a simple andinexpensive device and yet one which will be exceedingly effective i forthe purposes for which it is designed.

These objects I accomplish by means ofV such structure and relativearrangement of Specification of Letters Patent. Patentd ADI- 11, 1922.y

parts as will fully appear by, arperusal of .the (followingspecificationandv claim. L

. YIn the drawings similar characters ofreference indicatecorrespondingparts` in the several views.

Fig. 1 is a fragmentary side elevation of a wheel structure, viewed fromthe outer face of the same 'Fig'. 2 is a similar view With the outerdisk and valve hand-hole plate removed. F Fig 3 is a cross section on aline 3 3 of Y Referring now more particularly to the characters ofreference on the drawings, the numeral 1 denotes the fixed rim to theopposite and inner edges of which are xed the discs 2 of the wheel. Y

A vertical flange 3 projects outwardly from the inner edge of the rimand is adapted to seat thereon one flange of the demountable rim 4, thislatter being of the type shown in the aforementioned application forpatent thereon. A continuous lockwith said rim extendingrtransverselythereof, one on each side of and' adjacent said recess, these lugsterminating short of the outer periphery of the ange 3. Y

The demountable rim 4 is formed with an a central orifice 10 to receivethe valve stern 11Y of :the tire therethrough.

An air-valve hand hole plate 121 ofthe type shown-in the aforementioned`patentis mountedin the outer one of the discs 2 in alinernent kwith thevalve 11, which projectsY between the discs and beyond the boss 9, saidplate being cut radiallly to conform to the curvature of the inner edgeof the locking ring 5 and terminating thereagainst, so that when thewheel and its co-operating parts are assembled, the locking ring coversavportion of the rim-slot 7, while the plate 12y covers the remainder;

inwardly projecting boss 9 adapted to seat l snugly between the lugs 8and provided with In ythis manner, an unbroken appearance is had fromthe outside'of the wheel, while by removing the looking ring and valveplate, the demountable rim and tire may be removed from the wheel byslipping the same off without raising or offsetting the same in any way,

From the foregoing description it will be readily seen that I haveproduced such a device as substantially fullls the object of theinvention as set forth herein.

IVliile this specification sets forth in detail the present andpreferred construction of the device, still in practice such deviationsfrom such detail may be resorted to as do not form a departure from thespirit of the invention, as defined by the appended claim,

Having thus described my invention, What I claim as new and useful anddesire to se cure by Letters Patent is In combination, a fixed rim, ademount-v able rim adapted to be mounted thereon, a transverse slotprovided in the fixed rim and open from the outei` edge thereof, lugsprojecting outwardly from the sides of said slotl` a boss on thedemount-able rim adapted to seat between said lugs, and a locking ringfor the demountable rim adapted to pass across the outer face of theslot to nor.

mally conceal the same.

In testimony whereof I aix my signature.

LOUIS B. HARVEY.
